the locking mechanism mounted thereon. In fact, the action of an explosive in any one or all of these chambers or recesses will tend more firmly to seat the more substantial inner portion of the door the better to resist further operations, as well as for the better protection of the locking mechanism. The walls or ribs separating adjoining chambers or recesses may, if desired, be perforated, as at 0 to. place said chambers in communi cation with each other and by enlarging the chamber in which the explosive may act correspondingly reduce its effectiveness. These recesses or chambers between the'door portions also serve as heat-resisting or insulatingmeans to protect the contents of the safe. W

en the door is made as a casting, suitable o enings 0 Fig. 4, in any number are rovided to receive those parts of the 100' 'ng mechanism which must be accessible from the exterior of the door. Preferably these openings are -'made conical in sha e from front to rear, as best indicated in ig. 5, to ermit accuracy of fit of the parts introuced therethrough and at the same time to render it more diflicult for any instrument or explosive to be introduced thereat. While I have found in practice that it is ordinarily sufficient for the u'rposes of the invention to provide a door having an outer and relatively thin portion separated by one or more recesses or chambers from a relatively heavier inner portion, nevertheless my invention obviously includes the use of any desired number of door portions separated in any desired mannerv and graded as may be deemed best to resist operations likely to be conducted against it.

Referring now more particularly to Figs. 3 and 5, the door is provided at its inner ace with a circumferential flange d, throu h which are extended and in which slide t e lockin -bolts e, here shown as four in numh'ese bolts may be of rectangular or other cross-sectional shape and enter usual pockets e, Fig. 2, in the safe-body and pref-- erably near the inner wall thereof. The several bolts e are drilled and tapped to receive the threaded ends of the operating screws or actuators f, said screws at their inner ends' being passed loosely through the retainingwalls f, v are provided beyond said walls f with pmions 3", that are engaged by a common master or center wheel f for actuating them simultaneously and similarly. The bolt-actuating screws f are shouldered or collared at the opposite sides of their respective walls so that rotation of said screws will cause the bolts to be screwed outward and inward thereon for the pur ose of locking and unlocking the door. 11 small sizes these supportin -walls f will be yoke-shaped, as indicated in Fig. 3, for convenience in manufacture; but in the larger sizes said walls cast integrally with the door, and

may more conveniently be'--fornied as so many parts of, a single circular lip or flange concentric with the outer flange d. The common operating or master Wheelf is here shown as centrally mounted upon an inner cap or plate h, Fig: 5, suitably secured to the inner door-face and preferably countersunk in and so as to be flush with the inner face of the outer flange d.

In Fig. 5 the central aperture throu h the door is shown as receiving the conica spindle m, which at its inner end forms a part of any usual ordesired locking mechanism for operating the bolts and at itsouter end is squared or otherwise fitted, as indicated, to receive the operating mechanism of some form of lock or other applaratus arranged on or in connection with t e inner port on of the door. The inner end of said spindle m is shown as squared at m, so as to enter at the proper time the correspondingly-shaped recess m in the hub of the operating-wheel f for operating the latter from the outside ofthe safe-door. Said spindle is also shown as circumferentially grooved at one or more oints, as indicated at m, to improve the earing of the s indie and to render it more difiicult for exp osives to pass the same.

In the described embodiments of my invention it will be noted that the explosion chamber or chambers are 0 en at the periphery of the door and exten inwardly toward the center, and in every instance the spindlereceivin opening is surrounded by a wall, so as to re uce the liability of the gases entering the safe through the s indie-opening.

As already-sufficient y indicated, the door is so constructed that its outer portion yields most readily to the force of an explosion, and

-- since the convergence of the door-j amb is toward the interior of the safe there is no resistance to the blowing out of its outer portion, while the shorter diameter of the inner portion of the jamb cooperates with the corresponding configuration of the inner portion of the door to insure even a greater security of that portion of the door when, upon explosion, the outer portion has been blown away or ruptured.

My invention is not limited to the embodiments thereof here illustrated and described, forobviously they may be varied in many particulars within the spirit and scope of the invention disclosed.

What I claim is- 1. A safe, provided with a door-jamb, and a door arranged to be moved into and out of said jamb and having an explosion chamber or chambers extending inwardly from and open at its periphery, the substance of the door on opposite sides of the chamber or chambers being rigidly united and the outer portion adapted to be severed from the inner portion b the force of an ex losion within the cham er or chambers, wit out removing I chambers and interposed riphery, and rib like walls connecting the material of the door on opposite sides of the chambers.

10 3. A safe, provided with a single integral door, having a. number of explosion-cham- 11ers extending inwardly from and open 'at its periphery, and rib-like walls connecting the material of the door on o posite sides of the between the chambers, said rib-like walls having transverse perforations -for establishing intercommunication of'the chambers.

4.. A sate-door, made as a single casting,

having oneor more explosion-chambers ex- ,tending inwardly from and o ening, at the eriphery of the door the door avinga spindle-socket extending from -front to back through it, and the solid material of the door the spindle-socket and separating the soc et from the chamber.

'- 5 A safe-door, made as a singlecasting,

a number of radially-arranged explosion-chambers opening at its eriphery and rib-like walls separating said 0 ambers.

6. A safe door, made as an integer and iprrovided with a recess extending inwardly' om its periphery and 0 en at the periphery and constituting an exp osion-chamber, the substance of the door on opposite sides of the chamber being ri portion thinner t an the inner portion and ada ted to be ru tured or blown out under the orce of an exp losion within the explosionchamber.

In testimony whereof I have signed my name to this specification in the presence of two subscribing-witnesses.
